Buying a Used Car? 7 Red Flags to Watch For

August 29, 2025

Shopping for a used car can be exciting, especially when you find one that seems to match your budget and preferences. However, not every used car is a good deal. Some may have hidden problems that can cost you a lot more in repairs than you save on the purchase price. Knowing what warning signs to look for can help you avoid a bad investment.


Here are seven key red flags that should make you slow down and take a closer look before buying.


1. Unwillingness to Provide the Vehicle Title


A legitimate seller should have the title ready to show you. If they hesitate, claim it is lost, or say they will provide it later, proceed with caution. Without a clean, clear title in the seller's name, you cannot be sure the car is legally theirs to sell. It could also indicate there is a lien on the vehicle, meaning the seller still owes money on it. Always verify the title matches the VIN on the car.


2. Inconsistent or Missing Maintenance Records


A well-maintained vehicle typically comes with service records that show oil changes, repairs, and inspections over the years. If the seller cannot provide any maintenance history, there is no way to know if the car received proper care. This is not always a deal-breaker, but it does mean you will need to have the vehicle inspected more thoroughly before making a decision.


3. Fresh Paint or Body Work in Isolated Areas


While fresh paint might seem like a good thing, it can also be used to hide rust or accident damage. Examine the paint texture and color closely. If one panel looks newer or shinier than the rest, ask why. Check for overspray on trim, windows, or tires, which can indicate a quick, low-quality repair. Uneven gaps between body panels can also be a sign of previous collision damage.


4. Strong Odors Inside the Car


Pay attention to what you smell when you open the door. A musty or moldy smell can be a sign of water leaks or flood damage. Overly strong air fresheners may be used to mask unpleasant odors such as cigarette smoke or mildew. Both flood damage and persistent smoke odors can be difficult or even impossible to fully remove.


5. Warning Lights on the Dashboard


If any dashboard warning lights are illuminated during your test drive, that is a concern. Even if the car seems to run fine, a check engine light, ABS light, or airbag light can indicate serious problems. Some sellers will clear the codes temporarily, so it is wise to have the car scanned with a diagnostic tool to see if any hidden trouble codes are stored in the system.


6. Signs of Poor Previous Repairs


Look under the hood and in the trunk for evidence of sloppy repair work. Loose wires, mismatched parts, or non-factory modifications may indicate that previous owners made repairs without professional expertise. While some modifications are harmless, poorly executed repairs can create ongoing problems that are expensive to fix.


7. Seller Pushing for a Quick Sale


If the seller seems overly eager to rush the process, take a step back. Phrases like “I have another buyer coming today” or “You need to decide now” are often tactics to discourage you from asking too many questions. A trustworthy seller will allow you to take your time, arrange for an inspection, and review all documents before making a decision.


Protect Yourself with a Pre-Purchase Inspection


Even if none of these red flags are immediately obvious, a pre-purchase inspection by a trusted mechanic is one of the best ways to protect yourself. During this inspection, a technician will check the engine, transmission, brakes, suspension, and other key components. They can also look for hidden signs of flood damage, frame issues, or past accidents that may not be listed in the vehicle history report.


A small investment in an inspection can save you from buying a vehicle that needs thousands of dollars in repairs.


Use Vehicle History Reports Wisely


Services like Carfax or AutoCheck can reveal important information about a car’s history, including accident reports, title changes, and previous ownership. However, keep in mind that these reports are only as accurate as the information reported to them. Not all accidents or repairs make it into these databases, which is why combining a history report with an inspection gives you the best protection.
